Suppose we want to estimate the population mean body mass (in grams) of Adelie penguins in the Palmer Archipelago, Antarctica. In a random sample of 151 Adelie penguins, the average body mass was 3700.662 grams with a standard deviation of 458.566 grams. Calculate the lower bound of a 95% confidence interval to estimate the population mean described above. You can assume that the necessary conditions to construct a Student's t confidence interval to estimate u have been met. The critical value is 1.9759. Round your answer to three decimal places.
